About this entry

79% of key specs known. Missing: weight, hardening, end links, link attachment.

The SW200 builds (grade not stated) of two listings with the same quoted case, merged here: SN020-G3 (black or Tiffany blue dial; its ST2130 build is sn020-st2130) and SN020-G4 (black, sunray blue or light blue dial, logo only; its PT5000 build is sn020-pt5000), all at $456. Brand specs common to both: 316L, 39mm, 47.5mm lug-to-lug, 12.5mm (not stated whether that includes the crystal), 20mm lugs, sapphire with AR coating (side not stated), polished steel bezel (recorded as fixed with no insert), applied hour markers, "classic Mercedes" hands, BGW-9 blue lume on hands and markers, screw-down crown with 3D hexagon logo, brushed screw-down caseback, 316L bracelet with female end links, 20mm tapering to 16mm, folding clasp with safety and 4 micro-adjust holes (recorded as tool micro-adjust), 100m, about 138g on the G3 and 136g on the G4 (not stated what was weighed). The G3 listing calls its crystal "top hat" and its dials sterile; the G4 listing says neither, so the crystal shape is left blank. The G3 listing offers each dial with or without the logo at the same price. Inspired_by is read from the design (3-6-9 dial, Mercedes hands, smooth bezel) and the listing titles, which call it an "explorer"; the brand does not name the Rolex. The movement has a date but the photos show no date window, so complications are time only. Every variation showed "Out of stock" on 2026-10-24, so production status is unknown.
